Just upgraded from 16x to the latest build 8125.
In one of my accounts under activity I have a pop retrieval via 127.0.0.1 to another account on the server.
This stopped working after the upgrade.
I have two other retrievals for IMAP pointing to 127.0.0.1 and they work fine.
I did not change any settings after the upgrade. All bindings are the same and appear to be working just fine.
I can access the server for accounts via POP so POP is working as it should normally.
The only symptom is this one area.
Is this a configuration issue potentially or a bug in this build?
